Question 92439
{{{5/(2x^2) - 3/(x^2+2x) + 2/(x^2-4)}}}
To start, we to get rid of the denominator by multiply by a common factor, in this case, x^2+2x-4:
{{{(5/(2x^2))*(x^2+2x-4) - (3/(x^2+2x))*(x^2+2x-4) + (2/(x^2-4))*(x^2+2x-4)}}}
Cancel out leaving:
{{{5*(2x-4)/2 - 3*(-4) + 2(2x)}}}
Then simplify:
{{{(10x-20)/2 +12 +4x}}}
{{{5x - 10 + 12 +4x}}}
{{{9x+2}}}
